Abstract In black soil which for a long time was not fertilized, high content of mobile boron compounds is formed. Thus testing of soil on content of the mobile boron is considered the best method for determination of boron content in plants. There is opinion, that testing of plant tissues on boron content is less reliable, because its critical limits can not be easily determined due to the uneven accumulation of boron in plants tissues, changes of absorption of boron on the different stages of growth and lixiviating of boron from plants tissue during precipitations. It was set, that in the plants of winter wheat, grown on podzolized black soil without fertilization, the deficit of boron is formed. Probably, it is necessary to connect it with the extended correlation of calcium and boron content in plant samples. On the basis of these researches was proved, that for the objective estimation of boron emission in the plants of winter wheat we should not be restricted to determination of provision of soil with mobile boron. It is necessary to determine the content of compounds of boron and calcium in plants tissues.
